Here, we present a stalagmite-based reconstruction of tropical West Pacific hydroclimate from 570 to 210 ka. The results suggest similar regional precipitation amounts across the four interglacials contained in the record, implying that tropical hydroclimate was insensitive to interglacial differences in PCO2 and high-latitude temperature. In contrast, during glacial terminations, drying in the tropical West Pacific accompanied cooling events in northern high latitudes. Therefore, the tropical convective heat engine can either stabilize or amplify global climate change, depending on the nature of the climate forcing. STUDY NOTES: Oxygen and carbon stable isotope records (d18O and d13C) from three stalagmites collected in three different caves in Gunung Mulu and Gunung Buda National Parks, Northern Borneo, Malaysia. Chronologies were established by 238U-234U-230Th dating. Stalagmite GC08 was taken from Green Cathedral Cave in Gunung Buda, WR5 from Whiterock Cave in Gunung Mulu, and Squeeze1 was obtained from the connection between Clearwater and Wind Caves, in Gunung Mulu.
